A Successful Therapeutic Challenge: Local Reirradiation of Breast Cancer with a Single Dose of 18 Gy Intraoperative Radiation Therapy (IORT)

Abstract

After standard treatment of primary breast cancer, local relapse can develop in a previously irradiated region. The decision to refer a patient for a second radiotherapy must be thoroughly evaluated due to the increased risk of side effects. We report a case of a 43-year-old Caucasian female with a history of left breast lumpectomy and radiation treatment in 1990 for an invasive ductal carcinoma who presented with a locoregional recurrence 19 years later. After careful evaluation, the patient has undergone a second breast-conserving surgery and successful reirradiation with 18 Gy single dose of intraoperative radiation therapy (IORT).
